Problems : In the result my fields do not populate the Modules->Fields
they are created at the root node , If I change the order of my Rule StringFieldsToStringFields, String Items is created in the root node
I can't separate this rules because ATL do not accept multiple rules with the same source.

Any one could give me a solution ?

Thanks

Ps: Sorry I have a bad english, I am french and accept a english and french response

You better use the second option with resolveTemp because the resolution mechanism of ATL basically bind the "from" object to the first "to" object. By using resolveTemp you can reference the others "to" objects :
